and FRANCIS N. PALMER, citizens of' the United States, residing at Kenosha, in the county of AKenosha andStat'e' of Visconsin, respectively, haveinvented certain new and in Plumbing-Fixtures of which t e" following is a specification.v

This invention relates to improvements in lumbingixturesffand in the specific emodimentshown relates to an improved bath Among the salient objectsof the invention'v are vtoprovide a construction the parts of 15 guis'hedfrom analogous" structuresthe union 'V which may practically all be formed of tubing and: sheet metal union members; as distin' members of. which are largely formed of castinUs-g .to-1 provide a construction" lwhich en#` abllesa nurling'- or lspinning .tool tobeused uniting-most of theparts and in this rcyfor `specltiefl`ects aA better and more economical union; to provide a construction which whenzfcompletedpresents a more finished stub, afragmentary and.,='gracei`ul appearance and at the `same time' employs less metal in its construction, and'in struction of the .character referred to.

'lo the-above cnds'tlie invention consists in the "matters hereinafter described, and more particularly pointed out in the appended claims.

least-the foregoing is true as to a lgener proposition. In its broader aspect our inventionresides; ,f'f in utilizing spherical union members to whichk the othermembers are joined by spin'ningor"a nul'ling; the use of the' spherical shz tp `o`.lrv union enabli us to `join pipe sections ther 'toby the met 10d mentioned, 'as will'no described. Y

Describing the specific embodiment "off'th ii y invention union members 5, G and 7 at'the junctlirof the branch-pipes, at the point1 f con'lectiopgglo l with the' bottom of the bath v tub-end. yat

point of connection with the upper part o'f 1 the tub, res .ecti'veljsj- Each of t e three union members 5, 6 ja .-fz 7'is inthe main s herical; that is :to say, ea'oh'105 consists of a ho low sheet metal ball. The Q member has connected therewith, in` diametri' opposed relations, the pipes' 2 and rically 10 duced annular terminal portion 10 adapted to lit snugly in the aperture 8. ,The reduced portion 1() is conveniently formed by spinning,

in which case the internal diameter of the tube will be slightly reduced, although it wouldbe within our invention to form this reduced portion 10 by turning off the exteq rior of the tube. In either case an annular limiting shoulder 11 is formed at the point. where the reduced 'portion joinsthe main portion of thenipple', which shoulder serves as a sto i to limit. the insertion ofthe nipple inside tlic union'mem'ber. The two parts are next assembled and arotating tool in- `serted so as toextend axially in through the nipple-and having at its innerend an out-y turned spinning nose .or nurl which will engage the terminal edge of the reduced portion l0, and in the rotation of the tool expand' or spin said edge outwardly within the union member, as shoun elearl at 12 (Fig. (i). lt will be obvious that if t 'e member 5 be laccurately"spherical, and-the aperture 8 formed` therein' be truly circular, then the perimeter.' o f the a )ei-ture 8 will lie in'a plane and accordingly iil the nipple 9 haverits 'end out oli' at rivht angles to its axis the joint will not on! icltrulycircular but ,will be concentricwitli the longitudinalaxis of the nipple. Ynseuuc-.ntly when. thespinning o'r expanding tool is entered through the nipple. aiulrotated with-its axis of rotationV coincident with the .faxis of the tube,` the spinning 'operation will be aceuiately'and perfectly performed. l

'lo unite-the `main section of the tube with the ni pple, the latter is provided with an externa threaded portion 13, which in practice welind it .most advantageous to unite with-the nipple by sweating or soldering. v0f course, this portionmight bel formed integrally with 'the nipple. The main thluisection is made of such external danuiter as to, telescopeand lit closely within the nipple, and an internally threaded union ring 14 is arranged to lit upon the member I i. rlhis ring 14 is provided at one end with an intuned llange 15, the inner tiwri'tm-.tcr' -`ol' which extendsvclose to the '-.i\:torio r' of'the tube section, and between thier-flange and the? opposed end wall of the nipplev is--inti-.rposed a compressible,gasket `or packing ring lo. As the 'couplinf ring' is advanced upon thethreaded nippe the packing ring is com )ressed and thus made 651.0 sealthe connection"betweenthe nipple and the tube' the rictional gripfof the packing ring being sufficient to 'old 'thej tubeagainst endwise movement. Of course, the several nipples' 9 may be of any desired length and the union rings and' 70 connected ends of the tu s" thus located at varying distances from th unioiimember 5.y l In uniting the member kwith the branch pipie 3 the-nipple'membe is dispensed with .an

spherical'union membenf' As best shown "1 lin Figs, v3 and 4, the union member is-pro-- 'vided with an. aperture adapted toY receive the end of the tubemember 3, and in this instance to form the limi-ting or st o shoulder so 11 the tube' section' is provide `with anexternal `=bead 17.A This bead is convenft4 -iently formed by spinning Vin a familiar manner-. 'The y means of a suitable forming die, so that the bottom of the union member isintemallv-- convex, and, with the exce tionof, asma angle 19, raised above Athe owermostflevel 1915i ofthe interior of the v`pipe3.v l In lthey words, the water will tu drain-out except V6 hereinafter appear. l

To the upiper side of the union vmember 6 u is united a which collar is provided witha relativel short nipple-like, extension 21y which ls .fitted into Aa corresponding'aperture in the top of the union member and is expanded into the latter in substantially the same manner as is the pipe 3.' The under face of the flange body serves in this instance toj form the shoulder or stop which'liinits the insertionof the nipple portion. l To com lete4 the eonnectionof the fixture to the bat tub, a thimble ontrimmer'22 is' fitted into the a rture through the 'bottom` of the tube; tris thimble" comprising a tubular body 23, an out-turned 'ihm e124 and a spider 25 extendin acros's the ower end of the tubular bory 22. Centrally through the spider is 'formed ana" rture to receive aclamping screw 26, the owerfend of which en ages an Vinternally threaded stud 27, whleh is `united by riveting or otherwise withA the upper part of the convex bottom member 18.1 llhe bendin in of the; bottom of the union member us serves ,and brin rs vthe latter much" clos'erfto the bottom o the tubso that an much shorter screw can be used for uniting the parts.
